VT-d: split .ack and .disable DMA-MSI actors

Calling irq_complete_move() from .disable is wrong, breaking S3 resume.

Comparing with all other .ack actors, it was also missing a call to
move_{native,masked}_irq(). As the actor is masking its interrupt
anyway (albeit it's not immediately obvious why), the latter is the
better choice.
